Astronaut Robert L. Behnken used a digital camera to take this self-protrait during a spacewalk. Also visible in the visor's reflections are components of the station, the docked space shuttle Endeavour and a blue and white portion of Earth. During the nearly 7-hour spacewalk, Behnken and astronaut Rick Linnehan, installed a spare-parts platform and tool-handling assembly for the Special Purpose Dextrous Manipulator also known as Dextre. Among other tasks, they also and calibrated Dextre's end...

A blue-green veil of water tumbles 51 meters over the rocky precipice of the Niagara Falls in this Ikonos image, acquired on August 2, 2004. Every second, more than two million liters of water plummets over the half-circle of the Canadian/Horseshoe portion of the Niagara Falls, shown here, making it one of the world's largest waterfalls. The force of the pounding water is sending a cloud of mist up from the bottom of the falls; this same force eats away at the rock behind the falls, pushing...

Human history isn't confined to books; some of it is written across the surface of the Earth. Among the places where the earth itself tells a story of our past is the French landscape around the city of Verdun, where more than 300,000 French and Germans died during a World War I battle that went on from mid-February to mid-December 1916. In this image, Verdun is a small city on the banks of the Meuse River surrounded by the geometric pattern of farmed and fallow fields. The river is framed by...

MOPITT measures radiances in several channels to determine the amount of carbon monoxide (CO) and methane in the atmosphere. Channel 1 Difference radiances, shown here, are sensitive to the temperature of the earth's surface, the temperature of the atmosphere, and the amount of CO Of these, the first two effects dominate. Thus, we see red colors, indicating high radiances and high surface temperatures from the subtropical deserts (Sahara, Arabian, Rajastan and Kalahari). The blues indicate low...

Satellite remote sensors view the Earth at many scales of space, ranging from global through continental, regional, and local--even observing details as small as one meter (three feet) across. These data enable scientists to study a wide range of phenomena that occur over these same scales of space, such as El Nino, droughts, storms, and flash floods.

St. Helens volcano in Washington State was acquired on August 8, 2000 and covers an area of 37 by 51 km. Mount Saint Helens, a volcano in the Cascade Range of southwestern Washington that had been dormant since 1857, began to show signs of renewed activity in early 1980. On 18 May 1980, it erupted with such violence that the top of the mountain was blown off, spewing a cloud of ash...

The Strait of Messina Bridge Project, if completed, would stand as one of the landmark bridges of the 21st century. It would be the longest suspension bridge ever built. The Strait of Messina divides the island of Sicily from Calabria in southern Italy, and is 3 km wide. While the overall length is not a big problem, the economics, water depth, wind, and earthquakes all have to be accounted for. To avoid the problem of the deep water, the solution was to design the longest suspension bridge...

The torrent triggered flooding and mudslides that ran swiftly down the northern and southern flanks of the Massif de la Salle, straddling the border between Haiti and the Dominican Republic.

Nearly 30 years ago this week, a new era in space flight began, when on April 12, 1981 the first shuttle mission was launched. STS-1 commander John Young had already flown in space four times, including a walk on the moon in 1972. Bob Crippen, the pilot, was a Navy test pilot who would go on to command three future shuttle missions. Image Credit: NASA

On July 27, 1953, an armistice agreement brought fighting, though not the war itself, to an end in Korea. One legacy of that 50-year-old ceasefire has been the 250-km-long (148-mile) truce line bisecting the Korean Peninsula into northern and southern halves. The armistice provided for a 4-km-wide (2.5-mile) buffer zone running west to east roughly along the 38th parallel. This buffer zone contains river deltas and grasslands toward its western end, but is mostly mountainous terrain in the...

Previously, our galaxy was thought to possess four major arms. This artist's concept illustrates the new view of the Milky Way, along with other...

Viewed from the Banana River Viewing Site at NASA's Kennedy Space Center in Florida, space shuttle Discovery arcs through a cloud-brushed sky, lighted by the trail of fire after launch on the STS-128 mission. Liftoff from Launch Pad 39A was on time at 11:59 p.m. EDT. The first launch attempt on Aug. 24 was postponed due to unfavorable weather conditions. The second attempt on Aug. 25 also was postponed due to an issue with a valve in space shuttle Discovery's main propulsion system. The STS-128...

Remote-sensing devices that scientists use to observe the atmosphere come in two varieties: passive sensors and active sensors. A passive sensor detects light or heat of certain wavelengths that enters its field of view. An active sensor probes the environment by sending out a pulse of energy and measuring how long it takes the signal to return and how its frequency, wavelength, or intensity has changed. The energy pulse can be microwaves or radio waves (radar) or light (lidar). The images...

Astronomers have long known that the supermassive black hole at the center of the Milky Way Galaxy, known as Sagittarius A* (or Sgr A* for short), is a particularly poor eater. The fuel for this black hole comes from powerful winds blown off dozens of massive young stars that are concentrated nearby. These stars are located a relatively large distance away from Sgr A*, where the gravity of the black hole is weak, and so their high-velocity winds are difficult for the black hole to capture and...

Astronomers were surprised to find that star-formation activities in the outer regions of NGC 2976 have been virtually asleep because they shut down millions of years ago. The celebration is confined to a few die-hard partygoers huddled in the galaxyâs inner region. The explanation, astronomers say, is that a raucous interaction with M81, a neighboring group...
